Measuring 20 inches x 8 inches, it uses a 3-wire actuator to open and close airflow in ducted systems, with an integrated LED indicator that confirms damper position at a glance. Licensed HVAC technicians install this damper as part of a zoned forced-air system, connecting it to a zone control board to regulate conditioned air delivery to individual areas of a home. The 2-position design means the blade is either fully open or fully closed, making it straightforward to wire and commission on most residential zoning panels.\u003c\/p\u003e\n\u003cp\u003eThe ld-2008 is intended for residential ducted HVAC applications where independent temperature control is needed across multiple zones. It fits inline in rectangular ductwork measuring 20 inches x 8 inches and is controlled through a 3-wire low-voltage connection to a compatible zone control panel. The on-board LED simplifies troubleshooting during installation and routine service calls by providing a clear visual indication of the damper state without requiring a meter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRectangular form factor sized at 20 inches x 8 inches for direct inline duct installation\u003c\/li\u003e\n  \u003cli\u003e2-position operation — fully open or fully closed — for straightforward zone control\u003c\/li\u003e\n  \u003cli\u003e3-wire actuator for low-voltage connection to standard zone control boards\u003c\/li\u003e\n  \u003cli\u003eIntegrated LED indicator confirms damper position during installation and service\u003c\/li\u003e\n  \u003cli\u003eResidential-grade construction suited for forced-air zoning systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation zone damper for residential rectangular ductwork requiring a 20 inches x 8 inches 2-position damper with a 3-wire low-voltage actuator.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician familiar with low-voltage zoning systems. Shut off power to the air handler and zone control panel before wiring the actuator. The damper must be mounted inline in the supply duct with airflow direction matching the arrow or label on the damper body. Follow the zone control board manufacturer's wiring diagram for proper 3-wire actuator connections and verify LED operation before closing up the ductwork.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Rectangular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 20 inches x 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActuator Type\u003c\/strong\u003e: 3-Wire\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePosition Type\u003c\/strong\u003e: 2-Position (Open\/Closed)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLED Indicator\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Residential\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: IO HVAC CONTROLS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ld-2008\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IO HVAC CONTROLS","offers":[{"title":"Default Title","offer_id":51268172284210,"sku":"LD-2008","price":243.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308910675.jpg?v=1780701168","url":"https:\/\/voomisupply.com\/products\/io-hvac-controls-ld-2008-rectangular-zone-damper-20x8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
